Expression data from mouse IRF6 null and wt skin

ABSTRACT: Transcription factor paralogs may share a common role (e.g. Hox) in staged or overlapping expression in specific tissues. In other examples, members have distinct roles in a range of embryologic, differentiation or response pathways (e.g. Tbx, Pax). For the Interferon Regulatory Factor (IRF) family of transcription factors, mice deficient in Irf1, Irf2, Irf3, Irf4, Irf5, Irf7, Irf8 or Irf9, have defects in the immune response but display no embryologic abnormalities. Mice deficient for Irf6 have not been reported, but in humans, mutations in IRF6 cause two Mendelian orofacial clefting syndrome, and genetic variation in IRF6 confers risk for isolated cleft lip and palate. Mice deficient for Irf6 have abnormal skin, limb and craniofacial development. Histological and gene expression analyses indicate that the primary defect is in keratinocyte differentiation and proliferation. This study describes a novel role for an IRF family member in epidermal development. Keywords: Comparison of tissue from two genotypes

Embryonic transcriptome analysis of wt vs irf6-/- zebrafish at 4hpf

Project description:We report transcriptional profiles of 4hpf zebrafish embryos from either wild-type or a CRISPR-targeted irf6 loss-of-function mutant. Irf6 is a transcription factor implicated in syndromic and nonsyndromic forms of cleft palate. To define critical genes involved in palate development, we harvested RNA from irf6-/- embryos before an embryonic lethal stage in zebrafish and carried out RNA-sequencing and subsequent analysis. We identify top differentially expressed genes that include genes involved in periderm development, genes expressed in developmental processes (such as Fgfs and Wnt-pathway genes), and genes involved in orofacial clefting. We identify a crucial gene esrp1 that we chose for further validation and downstream analysis.

RNAseq E15.5 mouse skin WT, Irf6 KO, Ripk4 KD, and Irf6 S413A.S424A knockin

Project description:The integrity of the mammalian epidermis is essential for organism survival, and it depends on a balance of proliferation and differentiation in the resident stem cell population. The kinase Ripk4 and the transcription factor Irf6 are mutated in severe developmental syndromes in humans, and mice lacking these genes display epidermal hyperproliferation and soft tissue fusions, resulting in neonatal lethality. However, the mechanism by which these genes control epidermal differentiation in vivo is unknown. By generating various mouse knock-out and knock-in strains we demonstrate that in vivo the role of Ripk4 in development is dependent on its kinase activity, Ripk4 and Irf6 function cell autonomously in the epidermis,Ripk4 and Irf6 lie on a linear pathway and phosphorylation of Irf6 on Serine413 and Serine424 is essential to prime it for activation. This priming then allows Ripk4 to phosphorylate Irf6 on Serine90, which ensures Irf6 activation. We then use RNA-seq, ChIP-seq and ATAC-seq analysis to define the global transcriptional targets of Irf6 in epidermal differentiation. Collectively, our results explain how Ripk4 activates Irf6, and how this pathway ensures epidermal differentiation and a functional barrier. This is crucial for understanding the etiology of developmental syndromes that are characterized by orofacial, skin and genital abnormalities.

Interferon Regulatory Factor 6 (IRF6) knockout in human keratinocytes disrupts epithelial homeostasis

Project description:The transcription factor Interferon Regulatory Factor 6 (IRF6) is crucially involved in craniofacial development and regulates the proliferation/differentiation balance in keratinocytes. Pathological IRF6 variants have been found in Van der Woude syndrome (VWS), the most common syndromic form of cleft lip / palate (CLP) as well as in non-syndromic CLP cases. Besides its prominent function in regulating keratinocyte differentiation, recent data revealed that IRF6 is also involved in wound healing and migration. Since a significant fraction of CLP patients undergoing corrective cleft surgery experience wound healing complications, IRF6 represents an interesting candidate gene linking the two processes. However, Irf6 function has been mainly studied in mice and knowledge on IRF6 in human cells remains sparse. Here, we aimed to elucidate the role of IRF6 in human postnatal skin- and oral mucosa-derived keratinocytes by its ablation using CRISPR/Cas9. We complement this approach by applying proteomics and identify that lack of IRF6 disrupts human epithelial homeostasis by altering cell colony morphology, migration pattern, and the differentiation potential of keratinocytes.

Expression Profiling of Primary Human Proerythroblasts (ProEs) After IRF2, IRF6, and MYB shRNA Knockdown

Project description:IRF2, IRF6, and MYB are candidate regulators of human erythropoiesis. We here examine primary CD34+ hematopoietic stem/progenitor cells (HSPCs)-derived erythroid progenitors with control, IRF2, IRF6, or MYB shRNA lentiviral transduction prior to differentiation. Gene expression microarray profiling datasets for MYB shRNA and control shRNA were obtained from Gene Expression Omnibus (GEO) under accession number GSE25678. The data were analyzed together with the datasets obtained in this study. Primary maturing adult erythroblasts were generated ex vivo from CD34+ hematopoietic stem/progenitor cells (HSPCs) using a serum-free two-phase liquid culture system. CD34+ HSPCs were transduced with lentiviruses containing shRNAs against IRF2 or IRF6 gene, selected and differentiated to proerythroblasts (ProEs). Cells were harvested at day 5 of differentiated and total RNA were extracted. This was used to hybridize to Affymetrix expression arrays using the HG-U133 Plus 2.0 platform.
